Correction: The code shown above actually *does* work properly 
without any deprecation warnings. I made a mistake with the enum 
being set to the CTFE function I was previously using instead of 
this template. This template actually works.

I posted here for visibility and searchability, in case anyone 
else wants to do something like this.
